"You've just watched that episode," she said to him (she meant the one from tonight, with the intense final dinner party). "So tell us, why the emotion?"

ICYMI, the couples had to answer questions from the dreaded honesty box. Tracey was not pleased with Dean's answers, TBH. Especially the bit where he said he would have left if the tables had been turned – e.g. if Tracey had decided to emotionally cheat on him with someone called Davina.

So what made Dean finally get it, Jayne wanted to know. What made him see the error of his ways?

It wasn't the dinner party per se, Dean explained. Apparently his moral awakening (a Mills & Boon title if there's ever been one) had been building for a few weeks.

"I was starting to realise how it had affected people, and how it affected Tracey," he added, sounding remarkably like a regular human with feelings and a conscience.

"That night it all came to a head a little bit," he said.

"I maybe just pulled my head in a little bit. And had to be honest about it, I suppose."
